A funeral service for the late reality star was held Thursday in Chelsea, New York at the Trinity Grace Church, where her boyfriend Ryan Anderson, as well as reportedly some of her former Bachelor costars, paid their final respects to the 29-year-old beauty.

The NBA player was seen embracing Allemand's mother as they left the funeral service, all wearing yellow roses in remembrance of the late ABC star.

According to an eyewitness, there were "big crowds, lots of crying" and endless security at the service. Mourners also gathered outside the church, where there was a hearse with a large sign made of flowers spelling out Gia's name on top of the car.

Gia's NBA player boyfriend found her unconscious last week in her New Orleans home after she apparently hanged herself with a vacuum cord. She was taken to a nearby hospital where she was later pronounced dead.

According to an incident report obtained by E! News, Anderson told investigators that he and the 29-year-old dance instructor had argued through lunch on the afternoon of Aug. 12 "over her suspicions that he had been unfaithful to her."

Per the report, Anderson said he took Gia to a Walgreens to buy several items, including Nyquil cough syrup, before dropping her off at her apartment at around 6 p.m. Before she got out of the car, Allemand told him that she still loved him, to which he said he replied, "I don't love you anymore."

The New Orleans Pelicans player then returned home, he said, only to later receive a text from Allemand's mother saying he needed to go check on Gia, as they had been on phone and then the line just went silent for 10 minutes.

The athlete told police that he arrived at Allemand's house 20 minutes later, opened the door and found her unconscious with a vacuum cleaner cord "wrapped around her neck many times," the report states.

After Allemand's tragic passing, Anderson said in a statement that Gia "was the most beautiful person" he knew.

"She had such an amazing impact on my life and anyone that knew her was blessed," he said. "All I have left is to cherish those memories we made together and help perpetuate the many values, faith and love that we shared."
